Robotic Cleanup Arm Kit

Build a desktop robot that helps organize your stuff!

Create your own robotic arm that can pick up and move small objects around your desk or bedroom. Use rubber band power to make the gripper open and close, and manually position the arm to grab toys, pencils, or other lightweight items.

Assembly Instructions

  1. 1

    Step 1: Lay out all wooden panels, blue 3D-printed parts, screws, nuts, washers, dowel axles, and rubber bands.

  2. 2

    Step 2: Use the Allen key to screw the large base joint mount to the center of the platform with 4 screws, nuts, and washers.

  3. 3

    Step 3: Attach the elbow joint mount to one end of the first arm segment using 2 screws. This will be the 'shoulder' end.

  4. 4

    Step 4: Attach the wrist joint mount to one end of the second arm segment using 2 screws.

  5. 5

    Step 5: Screw the small gripper pivot mount to the left gripper jaw, and attach the rubber band hooks to both gripper jaws.

  6. 6

    Step 6: Insert the first 50mm axle through the base mount and the shoulder hole of arm segment 1. The arm should rotate freely.

  7. 7

    Step 7: Insert the second 50mm axle through the elbow mount and the shoulder hole of arm segment 2 to connect the two arm segments.

  8. 8

    Step 8: Insert the 40mm axle through the wrist mount and gripper pivot mount to attach the gripper assembly.

  9. 9

    Step 9: Slide the control handle onto the base axle so you can rotate the entire arm by turning the handle.

  10. 10

    Step 10: Stretch one rubber band between the two gripper hooks. The gripper jaws should close together when not held open.

  11. 11

    Step 11: Test your robotic arm! Hold the gripper jaws open, position the arm over a small object like a pencil or toy, then release to grab it.

  12. 12

    Step 12: Practice moving objects around your desk by positioning the arm segments and using the gripper to pick up and release items.

About This AI-Designed Building Kit

This Robotic Cleanup Arm Kit kit was designed entirely by artificial intelligence based on a young inventor's idea. Every InventShack kit features precision laser-cut 1/8" birchwood plywood panels, custom 3D-printed PLA components, and real M3 socket head cap screws with hex nuts — the same hardware used in real engineering projects.

Unlike mass-produced building kits, this design is one-of-a-kind. The AI selected from a library of parametric component templates — base plates, side panels, wheel discs, axle mounts, rubber band hooks, corner brackets, and more — then configured each part's dimensions to create a working build. All holes align to a 10mm grid system, ensuring every part connects properly.

Perfect for kids ages 8-10 who love building, inventing, and engineering. Whether you have a laser cutter, a 3D printer, or just want to see what AI can design — InventShack turns kids' ideas into real, buildable projects.
